摘要
作为空间形态研究的重要方法,量化分析被应用在不同尺度的城镇空间形态研究中。为揭示县域城镇空间形态量化指标的尺度变化规律,以长兴县为例,选取典型的形态指标,构建多层级缓冲区进行计算,分析指标随尺度变化的特征,探讨其适用尺度。研究显示:(1)各指标随尺度变化的趋势存在差异:土地利用混合度、开放空间率、水面率和绿地率随尺度增大而增大,容积率和开发密度则与之相反;(2)各指标的适用尺度有所不同:土地利用混合度适用于本研究中的各个尺度,容积率与开放空间率适用于社区及城市片区尺度,开发密度适用于城市片区尺度,道路面积率适用于社区尺度,水面率适用于街区尺度,绿地率适用于街区及社区尺度。
As an important method for spatial morphology research,quantitative analysis is applied to the study of town spatial morphology at different scales.In order to reveal the law of scale change of quantitative indicators for county town spatial morphology,taking Changxing County as an example,we select typical morphological indicators and construct multi-level buffers for calculations to analyse the characteristics of the indicators’change with scale and exploring their applicable scales.The results show that:(i)there are differences in the trend of scale change among the indicators:land use mixedness,open space rate,water surface rate and green space rate increase with broader scale,while the floor area ratio and development density show opposite trend.(ii)the applicable scales of each indicator are different:land use mixedness is applicable to all scales in this study,floor area ratio and open space rate are applicable to neighbourhood and urban area scales,development density is applicable to urban area scale,road area ratio is applicable to neighbourhood scale,water surface rate is applicable to block scale,and green space rate is applicable to block and neighbourhood scales.
